13.2 Chemical Formulas
... What is a chemical formula? Chemical formulas have two important parts: chemical symbols for the elements in the compound and subscripts that tell how many atoms of each element are needed to form the compound. The chemical formula for water, H2O, tells us that a water molecule is made of the elemen ...

Introduction to Chemical Reactions
... Chemical Equations are balanced to show the same number of atoms of each element on each side. The Law of Conservation of Mass says that atoms won’t be created or destroyed in a chemical reaction. That is why you have to balance chemical equations! ...
